EDGE-GUIDE FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application led October 27, 1906. Serial No. 340.804.

To all whom it may concern.'

Be it knownthat I, JOSEPH KosATKA, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Edge-Guides for Sewing- Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an edge-guide for sewing machines to be used in connection with a sewing machine of the ordinary and usual construction, in making stitched edges to garments, all kinds of welt seams, closed seams, piping, and in sewing on binding, tapes, and cords.

lWhile by the employment of my invention better results than at resent obtained may be' had in regard to al of the above operations, it is particularly adapted to the making of stitched edges, which to do well is known to all tailors to be one of the most difficult things in the art.

Heretofore in making stitched edges to garments, after the two pieces of material with the linings, canvas, etc., which are to form the edges, have been sewed together in the usual manner, the seam thus made is rolled out by hand in a manner well understood in the art and then basted to hold the two edges in position while being stitched on the machine. In the most expensive garments the greatest care must be used to force the seam out as faras possible and at the Sametime evenly throughout its entire length, when itis then basted, using stitches v close together and usually two or more rows of basting are ut in. At the present time in order to pus. out this seam the material has first to be rolled between the iingers, which requires a great deal `of pressure and is a very laborious operation. For this reason it isV difficult to get this work done by those who are capable of doing it correctly as it also makes the workers lingers sore and painful.

The fit of the garment depends very largely upon the manner in which the edges are stitched and this particular feature of the work is considered of importance. If the seam is not driven out to the very edge at every point throughout its entire vlength the garment will not hang well, and folds and wrinkles will appear after the edges have been stitched; and very often the ed es will flare. In order to reduce these wrink es and folds the edges will have to be pressed with a hot fiat-iron, and unless the pressing is properly done the wrinkles and folds will again appear, and if done with the modern high pressure machines the edges will flare.

By the em loyment of my invention, in a manner to lie hereinafter described, the seam is properly driven out to the edge of the material uniformly throughout its length, so that the stitching will be at uniform distance from the seam, doing away with the rolling of the material by the fingers and the usual basting.

In the accompanying drawings-Figure 1 isa top plan view of a device embodying my invention, mounted upon the table of a sewing machine Fig. 2 is a side view in elevation of the same, showing also certain parts secured to the lunder side of the table; Fig. 3 is a view on the line 3-3 of Fig. 2, parts being shown in section and parts in side elevation;

Fig. 4 is a detail cross-sectional view of the' view on the line 6 6 of Fig. 4; Fig.l 7 is a plan view of a raising plate which may be employed; and Fig. 8 is a view showing the operation of my invention upon the sewed edges. v

Like figures refer to the same parts throughout all the drawings.

In the drawings, 9 is the table of a sewing machine of the usual or ordinary type, 10 a metal spool-shaped standard which is longitudinally bored to receive a cylindrical guide post 11, which, together with all of the other parts is of metal, and is provided with threads adapted to engage a screw-threaded aperture in the base plate 12. The standard 10 is also bored transversely to receive a horizontal cylinder 13, which is of a suitable thickness to give the required strength for the purposes hereinafter set forth and is secured thereto by the binding screw 14. The base plate 12 carries two guides 15 and 16 on opposite sides of the standard 10, and a post 17, at one side of the line of the cylinder 13,

' the guides 15 and 16 being adapted to loosely receive binding rods 18 and 19, respectively, which also pass through the base plate 12 and table 9 yas is clearly shown in Fig. 3. The

post 17 supports a stop 20 which is slotted to receive the adjusting screw 21 which binds it to the said post. The cylinder 13 is provided at lits ends with 'plugs 22 which are rigidly secured thereto by the screws 23. The

plugs are of suitable 'thickness to furnish the proper strength required and are provided with squared apertures to loosely receive the square rod 24, to4 which an arm 25 is rigidly secured by means of the bolt 26 and the nut 27. The cap 28 of the standard is provided with ears 29 and 30 through which the ends of the binding rods 18 and 19 pass and receive the nuts 31 which when set rest and bear upon the said ears. The cap is recessed or hollowed out on its under side and carries in such recess a spring 32 which in the form shown is bowed and connected by screws 33 and bears upon a plug 34 which in turn bears yupon the rod 24 to rigidly hold it in operative position.

The cylinder 13 at its upper side is provided with an aperture adapted to receive the plug 34, which is preferably cylindrical in shape and fits snugly in the longitudinal bore of the standard 10 with itsupper and lower flat faces `in engagement with the spring 32 and the rod 24, respectively. The binding screw 35 holds the rod 24 in frictional engagement with the plugs 22 and thereby assists in securely holding the rod 24 in operative position. The rod 24 carries an adjustable collar 36 which may be securely held in .position by an adjusting screw 37, the purpose of which will hereinafter appear. .The standard 10 with its associated. parts is adapted to be raised, for a purpose to be more clearly set forth hereinafter, by the `employment of one or more raising plates 38,

adapted to be inserted between lthe standard 10 and base 12, and each of which is slotted as at 39 to engage the guide post 11 and is held in position by a set screw 40 engaging an open slot 41 in a projection thereof. The lowerends ofthe binding rods 18 and 19 pass through the ends of a cross beam 42, which is reduced at its ends as shown in Fig. 3, and receive nuts 43 wlnch when in operative position bearupon the ends of the said` cross beam.

The outer end of the arm 25 is adapted to receive a holder in the form of a hollow cyl inder 44 which is held in rigid engagement therewith by means of the binding screvif 45. The holder 44 is provided at its ends with plugs 46 and 47 which are secured thereto by means of the screws 48 and are provided with yapertures adapted to loosely receive the particular uses of which will hereinafter more fully appear, and which are secured to the rod 49 by means of adjusting screws 55. A

supplemental coil spring 56 surrounds the rod 49 between the plug 47 and the collar 54, said spring not being normally under iension. rlhe rod 49 carries an edge presser or guide 57 which is dctachably fastened thereto by means of screws 58. 'lhe edge guide may be of any suitable form and preferably is provided., at its free end with a yoke 59 adapted to receive a wheel 69 -which is free to revolve upon its axle 61. The gage 62 and adjusting screw 63 and the throat plate 64 are of any suitable form and construction.

A shaft 65 is ournaled in suitable hangers 66 attached to the under side of the table, and carries at its inner end a cam 67 which bears upon the cross beam 42. At its outer end the shaft is provided with a collar 68 secured by means of a screw 69 or other suitable means. Thel collar has a depending hollow elbow 70 in which a leg 71 is secured at a right angle to the shaft 65. '.l`he leg 71 at its lower extremity is bent at right angles in the direction parallel to the length of the shaft 65 and carries a foot rest 72 which rocks thereon and is prevented. from slipping olf by means of the pin 73. A coilv spring 74 has one of its ends attached to the leg 71 and the other end to the under side of the table 9 in any suitable manner, and a second coil spring 75 is attached. to the leg at the same point and has its other end secured to the. toe of the foot rest 72.

The shaft 65 extends beyond the collar 68 and carries a ratchet wheel 76, secured thereto in any suitable manner, with which a pawl 77 coacts to hold the shaft 65 against turning in one direction, the pawl being sup ported in a hanger 78 attached to the underside of the table 9. O ne end of a chain 79 is attached to the free end of the pawl, its other end being connected to the toe of the footrest 72. A stop 8() is secured to the under side of the table ,to limit the movement oll the leg under the tension of the spring 74.

As material of many dil'l'ercnt thicknesses may be stitched with my device, in order to raise the wheel 6() so that it will properly engage and force out thc seam which is to form the edges to be stitched, one or more of the raising plates 38 may be inserted between the base plate 12 and the standard 16, according to the thickness of the material.

Vhen the wheel 60 has been properly adjusted the operator places his foot u )on the foot rest 72 and moves the leg 71 lorward until it occupies a positionv shown in dotted lines in Fig 3. The leg 71 thus rocks the shaft 65 and the cam 67 presses down the cross beam 42. As the cross beam 42 is pressed down the cap which. is in operative connection with it by means of the, binding posts 18 and 19, is likewise drawn down to force the spring 32 down hard upon the plug 34 which in turn bears upon the rod 24 and thus holds it in rigid engagement with the plugs in the cylinder 13. When the leg 71 is thus moved forward far enough to produce the required pressure upon the cross beam 42, it is held in this position by means release the pressure on the rod 24. When the parts are thus released the arm 25 and its associated parts may be swung out of operative position by turning the standard 1() on the post 11, as shown in dotted' lines in Fig. 1. When the operator desires to use my device he swings the arm backagain until it comes in contact with,the stop 20 which is so adjusted that it stops the arm with the wheel 60 in the correct position for use.

In order that my invention may work to the best advantage with certain kinds of material,such as thin cloth, it is desirable to maintain rigidity of the several parts, and

the construction disclosed has proved to be most satisfactory. While it is possible to secure the requisite rigidity of the parts when in operative position, in Ways other than that disclosed, I have found that the means as illustrated by. the accompanying drawings is satisfactory as by the use of it the operator may secure the requisite rigid ity with no loss of time. When thicker material is employed, satisfactory results may be obtained by releasing the binding screw 50, adjusting the wheel 60 to the proper position with reference to the gage 62 in which it is maintained by the spring 51 and then sliding the collar 54 into engagement with the holder 44 and securing it to the rod 49 by the adjusting screw 55 which thus prevents the wheel 60 under the action of the spring 51 u on the rod 49 from being pushed nearer to t e gage than the predetermined distance. Of course as i the material is stitched the wheel may give a little, due to the unevenness in the seam, but this is controlled by the spring 51 which at once forces the wheel back to its roper position. The spring 56 is so adjusted) that it is not brought into use by the collar 54 until the spring 51 is contracted to a certain extent and then the spring 56 aids in'holding the edge-guide up to the work. The adjusting of the collar 54 controls the point at which the spring 56 is brought into service.

I have illustrated one use of my invention by showing its application to making stitched edges. In Fig. 8 the edge-guide presses against the seam 86 made by sewing the two pieces of material 87 together and as the material is fed along the throat plate 64 the wheel forces the seam out and presses it against the gage 62 and in position for the needle 85 to stitch the two edges uniformly.
